Albedo Effects on Weather and Climate

The video tutorial explains albedo, the fraction of solar radiation reflected by Earth's surface. It covers how different surfaces, like water, ground, and snow, have varying albedo values. The Earth's average albedo is around 30-35%, but it varies due to geological and environmental factors. Albedo significantly impacts climate and weather, influencing seasonal changes and temperature variations, especially after snowstorms.

What is albedo primarily concerned with?

• The transmission of solar radiation

• The emission of solar radiation

• The reflection of solar radiation

• The absorption of solar radiation

Which surface has the lowest albedo value?

• Fresh snow

• Water

• Vegetation

• Bare ground

What is the typical albedo range for crops or vegetation?

• 15-30%

• 30-50%

• 10-20%

• 0-10%

What is the Earth's average albedo percentage?

• 10-15%

• 20-25%

• 30-35%

• 40-45%

Which factor does NOT influence the Earth's albedo?

• Geologic features

• Environmental features

• The Earth's core temperature

• Seasonal changes

How does the Earth's tilt affect albedo?

• It increases albedo uniformly

• It decreases albedo uniformly

• It causes seasonal variations in albedo

• It causes no change in albedo

What happens to the albedo of a region in winter?

• It fluctuates randomly

• It increases

• It remains the same

• It decreases

Why does fresh snow lead to colder temperatures?

• It emits more heat

• It reflects more sunlight

• It absorbs more sunlight

• It traps more heat

Which of the following is a short-term effect of albedo on weather?

• Sudden increase in humidity

• Gradual warming over decades

• Long-term climate change

• Immediate temperature drop after snowfall

What is the primary reason for colder temperatures after a snowstorm?

• Decreased absorption of sunlight

• Increased reflection of sunlight

• Decreased reflection of sunlight

• Increased absorption of sunlight
